建筑基础设计中考虑风和地震荷载作用的设计方法探讨

Discussion on Design Method of the Role of Wind and Earthquake Loads in the Design of Building Foundation

近年来,随着建筑设计行业的发展,建筑物越来越高,风和地震荷载作用对建筑物的影响也越来越不可忽视。同时,行业规范的不断完善和建筑成本投入水平的提高,给基础设计考虑风和地震影响提供了条件。根据现行规范,按地基承载力确定基础底面积及埋深或按单桩承载力确定桩数时,传至基础或承台底面上的作用效应需按正常使用极限状态下作用的标准组合;应按规范的相关规定,具体考虑水平作用(包括风和地震)。

With the development of architectural design industry in recent years,the building height is higher and higher,the influence of wind and earthquake loads on buildings is more and more important.According to the current standard,according to determine the base area and buried depth of pile or pile number is determined when the bearing capacity of the bearing capacity of the foundation,to the base or bottom of cap on the effect should be standard combination according to the normal limit condition;the need to consider the level of action（including wind and earthquake）,considering the specific method of specification given the relevant provisions.
